Our yokeshaft/sleeve style 3.5" x .125" aluminum driveshaft if the perfect match for your 6L80, 6L90, 8L90, 10L80 or TR6060 and TR3160 swap. We exclusively use the SONNAX yokesaft/sleeve units because of their superior strength, fit, and finish. We pair this with the SONNAX T35-GMFD-01K 6061-T6 Alumimum 3-Bolt flange to seamlessly mate to these transmission: direct fit with no adapters. The SONNAX flange side of this shaft is a 1350 series u-joint, and the rear u-joint is up to your selection. This shaft is built with forged solid-cross non-greasable u-joints for unbeatable strength and longevity.
